Manual/ Hydraulic Control Tool Trap

Manual/ Hydraulic Control Tool Trap

The tool trap is mainly used for preventing instruments from falling into the well because the cable is accidently stretched breaking or released after the instrument sting is lifted to the lubricator from the well. The tool trap is normally closed when it is stopped and is put into the well to work.

When the whole set of the BOP is connected on the wellhead to work, firstly open the valve on the wellhead to make well liquid enter the lubricator, after the liquid is stable and the instrument string is uplifted for a certain distance, make the instruments leave off the shifting fork of the tool trap. The hydraulic control system is pressurized to lead the piston to push the operation arm to rotate along the rotary shaft, which leads the shifting fork mounted on the rotary shaft to be erected vertically, and then the shifting fork is totally opened, thereby opening the i.d. to put the instruments into the well. At this time, the cable is released down, the instrument string in the lubricator will enter the well successfully. After the instruments pass through the tool trap, hydraulic control pressure is not released, is automatically reset to the horizontal position by spring force. After the instrument string passes through the trap, if pressure for controlling the trap in the hydraulic control and grease injection pressure control system is released, the shifting fork will be automatically reset to the original horizontal position, namely the shifting fork is closed. When the instrument strip is upwards lifted, after the instrument strip is lifted to the tool trap from the well, the rope socket for connecting the instrument string will jack the shifting fork and enter the lubricator, when the instrument string is upwards lifted to leave the tool trap, the shifting fork will be automatically reset to the horizontal status, thereby preventing instruments from falling into well after the cable is stretched breaking accidently or released.
